Convert image URL to File instance

Question

I have an array of image data and am trying to convert it to a filearray

const images = [
  { img: "http://localhost/images/1.jpg", name: "1.png", mime_type: "image/jpeg" },
  { img: "http://localhost/images/2.jpg", name: "2.png", mime_type: "image/jpeg" },
]
const res: File[] = images.map(function (item) {
  return new File([item.img], item.name, { type: item.mime_type })
})

This doesn't work :(As I understand it, the converted image in base24 should be passed to the file constructor? How do I do that?

Update: I have a VUE component that handles images. The input component has a property of type array. How to create an array based on the data returned by the database. Returns from database: image link, name and type.

UPD2 answer:

let PhotosAsFile: File[] = []
const _photos = [
  { url: "http://localhost:8080/images/1.jpeg", name: "name1", mime_type: "image/jpeg" },
  { url: "http://localhost:8080/images/2.jpeg", name: "name2", mime_type: "image/jpeg" },
  { url: "http://localhost:8080/images/3.jpeg", name: "name3", mime_type: "image/jpeg" },
]

const data: Promise<File>[] = _photos.map(async function (item): Promise<File> {
  const myBlob: Blob = await getBlobFromUrl(item.url)
  const extensionsFile: RegExpMatchArray | null | undefined = item.url?.match(/\.([^.] )$/)

  return new File([myBlob], extensionsFile && item.name ? item.name "." extensionsFile[1] : "image.jpeg", {
    type: item.mime_type ?? "image/jpeg",
  })
})

Promise.all(data).then((values: File[]): void => {
  PhotosAsFile = values
})

const getBlobFromUrl = (url): Promise<Blob> => {
  return new Promise((resolve, reject): void => {
    const request: XMLHttpRequest = new XMLHttpRequest()
    request.open("GET", url, true)
    request.responseType = "blob"
    request.onload = () => {
      resolve(request.response)
    }
    request.onerror = reject
    request.send()
  })
}

To create the file (I'm not sure why you need it), you need to pass in the binary data

https://developer.mozilla.org/en -US/docs/Web/API/File/File

This is a file in memory. You cannot read it from disk. You cannot write it to disk. I guess you can set it to a value and send it as FormData.
